Texts I can send him to make him melt?

its a very complicated situation, but we're basically boyfriend and girlfriend. tonight about 30 minutes ago I sent him a text that said "good night... dream of me" what will he think of that? so he liked when I sent him one that said "I'm thinking of you" and tonight I also asked "r you thinking about me?" he said "i was" and thought it was really sweet. I like to send him stuff like that because then he knows how much I care about him, I also sometimes get these from him, so what kinds of things can I do to get a conversation going, and to make him speechless?

Updates:

i want suggestions... not reassurance... or telling me not to just text him, he lives far from me and we don't see each other much, so we text.

After our first date (*excellent* date), I found a way that she could hear a rare CD she'd been hunting for years -- and hear it free of charge. So I mentioned the website to her, and she said, "You found that! Wow! You're amazing! Where have you been all my life?" She was surprised and it just gushed out of her.

Well... the truth is there is another girl complicating the situation..... she means nothing, but I really like your idea. I was thinking of doing this "you are my boyfriend... you gonna get rid of her yet?" what do you think?

I just don't know how well it'll work, I mean he's not really dominant but he will be eventually I can tell, but he's the shy quiet type that took forever to even kiss me.... how do I not scare him off? I can literally see us together forever.
